Outrunner wheel hub motors – An optimal drive solution for any transport task

The extremely flat design of the wheel hub motors combined with a high power density allows an application with very tight installation spaces. The compact all-in-one solution not only impresses due to its benefits in terms of space requirements but also thanks to the fact it is maintenance-free and has a service life many times longer than systems equipped with a gearbox. The i-Wheel 3213 series consist of three high performance wheel hub drives, which can reach torques up to 34 Nm and speeds up to 27 km/h. In terms of its efficiency and individual scalability, the family of drives offers an optimal modular solution for electric transportation vehicles.

We would be pleased to develop a solution for you that is specially tailored to your drive task! Motor layout and flange geometry of the wheel hub drives as well as the type of brake and the encoder can be implemented in line with your requirements.

Wheel hub motors by Ketterer are ultra-compact

The ultra-compact design of our wheel hub motors enables a simple arrangement oft wo drives on one rotary disk. This means that maneuvering the vehicle with a zero turning radius is no longer a challenge.

Our technology - Your benefit

• Neither a gearbox nor an extra motor is needed
• Ultra-compact for tight installation spaces
• High power density in the smallest installation space
• Much longer service life compared to conventional drive technology with a gear stage
• No gear – no wear
• Easy replacement of wheel coating on site possible thanks to patented Ketterer solution
• Very good running properties with minimal noise level

Safety first

• Safety architecture of the rotational control system using diverse redundancy, or two-channel design
• In combination with a suitable controller, a safety level of PL-d in accordance with EN ISO 13849-1 can be achieved
• Safe production processes, as there are no risks of contamination from gear oils and greases (no gearbox)

Flexibility and customer orientation are our strengths: The choice is yours - we implement it!
